The provider toggle, schema, template, and NotificationService.on_printer_offline
all shipped, but no caller invoked the dispatcher — the offline event was an
orphan toggle. Edge detection in on_printer_status_change now schedules a
debounced (60s) background task on the connected→disconnected transition;
reconnect before the window elapses cancels it. Covers both upstream paths
(smart-plug power-off via mark_printer_offline, and MQTT staleness via
check_staleness), both of which already route through the status callback.
The "back online" channel is the existing print-failure notification on
firmware FAILED report — no symmetric on_printer_online needed.
VP queue-mode multi-plate Send All
==========================================
BambuStudio / OrcaSlicer "Send All" of a multi-plate project uploads ONE
3MF containing every plate (one FTP STOR, single filename) — slice_info.config
inside the file lists N <plate> blocks with their own index metadata and
their own Metadata/plate_N.gcode payload. Pre-#1733 the VP queue path
called _extract_plate_id which returned only the FIRST plate index, and
_add_to_print_queue built exactly one PrintQueueItem from it. Plates 2..N
silently dropped on the floor. From the user's perspective: Send All of a
3-plate project produced 1 queue item, indistinguishable from a regular
single-plate Send, with no log line to explain the discrepancy.
The wire was confirmed against the live H2D-1 Proxy VP: the same file
ships whether the user clicked Send or Send All; the only intent signal
is the count of <plate> blocks inside slice_info.config.
Fix: replaced _extract_plate_id (-> int | None) with _extract_plate_ids
(-> list[int]). The list contains every <plate> block's index in order;
falls back to [1] when slice_info.config is missing / unparseable so the
single-plate case is preserved. _add_to_print_queue now loops over the
list and creates one PrintQueueItem per plate, with:
- plate-specific position = MAX(position) + iteration_number, so the
items inherit consecutive positions and the slicer's plate order
becomes the queue execution order.
- per-plate required_filament_types / filament_overrides via
extract_filament_requirements(file_path, plate_id) — the plate-aware
filter shipped with #1697 — so the scheduler's per-printer "Any X"
matching dispatches each plate onto a printer with the right
colours loaded for THAT plate, not for plate 1's filament set.
- shared archive_id across all plates (one upload = one archive row).
- the VP's auto_dispatch + manual_start posture inherited unchanged.
Net behaviour: single-plate Send hits the loop once → exactly today's
result (one queue item, plate_id from the slicer, one archive). Multi-
plate Send All of a 3-plate file → 3 queue items, plate_id 1/2/3,
consecutive positions, all referencing the same backing archive.
Archive delete cascades to queue rows
=============================================
Previously the soft-delete path (the default the trash-can button uses)
called _cancel_pending_queue_items which only flipped queue rows with
status='pending' to status='cancelled' while leaving every other status
alone AND leaving every row in the DB. The Send All multi-plate work
above made this much more visible: deleting an archive backed by N
queue items now had to clean up N rows, and what users saw instead was
N "cancelled" rows lingering in the queue history.
Backend:
- Replaced _cancel_pending_queue_items with _delete_related_queue_items
(db, archive_id) -> int. DELETEs every queue row where
archive_id = X regardless of status. Matches what the hard-delete
path already did via the ON DELETE CASCADE FK on
print_queue.archive_id — both paths now produce the same end state.
- Print history lives in PrintLogEntry (FK ON DELETE SET NULL) and is
untouched; Quick Stats / accuracy bands are preserved across both
delete paths.
- 409 guard on archives.py::delete_archive when any related queue
item is currently status='printing'. Both soft and hard delete are
gated; deleting the archive while a print is live would strip the
dispatcher's metadata trail (filament / plate / ams_mapping) out
from under the running print.
- New GET /archives/{id}/delete-impact endpoint returns
{related_queue_items: N, currently_printing: M}. Cheap, single
endpoint, deliberately NOT folded into the archive list response
so the much larger list endpoint isn't forced to run the same
query per row.
Frontend:
- ArchivesPage delete-confirm modal queries the new endpoint when the
modal opens (useQuery with enabled: showDeleteConfirm) and renders
an amber "N queue items linked to this archive will also be removed"
line when total > 0 AND printing = 0, OR a red "Cannot delete —
M queue items are currently printing" line when printing > 0
(confirm button disabled in that case so the user can't bonk the
409 on submit).
- ConfirmModal gained an optional confirmDisabled?: boolean prop —
isLoading was the only disable knob before; this adds the external-
precondition path.
- 2 new i18n keys (deleteQueueItemsWarning, deleteBlockedByPrinting)
translated across all 11 locales per feedback_translate_dont_fallback —
no English fallbacks.
No DB migration — the CASCADE FK was already in place; only the helper's
semantics changed.
capture_finish_photo (default-on) was forcing the timelapse MQTT field to
true on every print, even when the user explicitly unchecked Timelapse in
the slicer send dialog. On profiles with Timelapse Type = Smooth, that
flipped the printer's timelapse_record_flag and un-gated the per-layer
M622 J1 wipe blocks the slicer had baked in — toolhead parked off the
part every layer, on prints the user opted out of recording.
Root cause: #1397 implemented the finish-photo feature as a side channel
of "force the printer into timelapse-recording mode at dispatch" so the
last-frame extractor had a video to pull from. That conflated recording a
timelapse with snapping a finish photo, and the per-layer side effects
were decided at slice time by the user's timelapse_type, which Bambuddy
has no visibility into post-slice.
Fix: replace the force-on with a clean MQTT-state-driven trigger.
bambu_mqtt.py fires a new on_finish_photo_moment callback when
stg_cur transitions INTO 22 ("Filament unloading") while
_was_running AND end-of-print gate matches (progress >= 99 OR
layer_num >= total_layers OR remaining_time <= 0). The gate
disambiguates from mid-print color swaps (which also transit
stage 22 but at progress < 99). FINISH-state fallback in the same
handler fires the callback at the existing transition if stage 22
never arrived (cancel, external-spool-only, HMS halt, firmware
variants).
main.py registers on_finish_photo_moment as a top-level handler.
It pre-captures one camera frame at the trigger edge (external cam
→ buffered RTSP → fresh RTSP via capture_camera_frame_bytes) and
caches the JPEG bytes in _stage22_finish_frames[printer_id].
_background_finish_photo consumes the cached bytes before its
existing live-grab chain, so the saved photo has the better
framing (toolhead parked, before bed drop) without restructuring
the archive-resolution / fallback / notification wiring.
When a timelapse IS actively recording (user explicitly opted in),
pre-capture is skipped — _capture_finish_photo_from_timelapse
still extracts the last frame, which is still the best framing
and now has no force-on side effects because the user wanted the
video.
Removed: resolve_effective_timelapse, _resolve_effective_timelapse
wrapper, both background_dispatch call sites, the print_scheduler call
site, the archive.bambuddy_forced_timelapse write, _cleanup_forced_timelapse
(~75 lines including the FTP-DELE walk across /timelapse, /timelapse/video,
/record, /recording) and its call site. All paths now read
bool(item.timelapse) / bool(job.options.get("timelapse", False)) directly.
The archive.bambuddy_forced_timelapse DB column stays defined (default
False) for back-compat with existing rows — no consumer reads it anymore.
VP bridges bound to a target printer (Proxy mode, Queue mode with
specific target) forwarded the printer's raw AMS push_status to the
slicer untouched. bambu_mqtt.py::_handle_ams_data applies a
tray_exist_bits-driven cleanup to Bambuddy's internal state
(promote empty slots to state=9, wipe stale tray_type / tray_color /
tray_info_idx / tag_uid / tray_uuid / remain) so the AMS card renders
empty slots as Empty, but the VP bridge cache never ran the same
cleanup. Net result on real hardware: a printer with 3 loaded
filaments and several previously-loaded-now-empty slots had Bambuddy's
AMS card render those slots correctly as Empty, but BambuStudio after
Sync painted them as phantom loaded filaments with stale color and
material from before the slot went empty.
Root cause: two consumers of the same payload, only one wired to the
cleanup. _handle_ams_data ran it on every push; mqtt_bridge.py::
_on_printer_raw merged the ams blob via _merge_ams_dict but copied
tray_exist_bits through as an opaque scalar without acting on it.
Fix: factored the bit-clear logic out of _handle_ams_data into a
module-level helper apply_tray_exist_bits(units, tray_exist_bits_str,
*, power_on_flag, log_label). Internal path replaced with a single
call. Bridge calls it after _merge_ams_dict on the merged ams dict,
before the merged state is stored as the 1 Hz cached-as-base source.
Shared shutdown guard kept on both sides: all-zero bits +
power_on_flag=False is the printer-off pattern (#765, would
propagate phantom empties on every reconnect); nonzero bits +
power-off is valid idle-printer state (#1365, X1C between prints)
and still applies. AMS-HT units (id >= 128) skipped on both sides.
Tests: new TestApplyTrayExistBitsHelper (10 cases) pins the helper
contract directly. 3 new bridge regression tests reproduce the
#1726 wire shape, the shutdown guard, and the AMS-HT skip on the
cached slicer-facing state. Existing internal-state tests for the
bit-clear logic (covers state=9 promotion, loaded-slot preserve,
genuine-removal-with-power-on) continue to pass against the
refactored path.
One pre-existing bridge fixture had an inconsistent tray_exist_bits
('3' for 2 AMS units each with slot 0 loaded — bit 4 missing). The
shared cleanup exposed it; corrected to '11' (bits 0 + 4) to match
real-printer wire shape.
Reported by @needo37 with full code-level analysis including the
suggested fix shape and the BAMBUDDY_VP_DUMP_WIRE diagnostic to
verify on a live system.
The Windows installer's embedded Python doesn't carry an IANA tz
database, and the stdlib zoneinfo has no system DB to read on Windows.
ZoneInfo("UTC") raises ZoneInfoNotFoundError on those installs, and
the new /api/local-backup/status endpoint 500s on the resulting
uncaught exception. Surfaced via a Windows traceback from a user's log:
File "...\backend\app\services\local_backup.py", line 32, in _local_zone
return ZoneInfo("UTC")
zoneinfo._common.ZoneInfoNotFoundError: 'No time zone found with key UTC'
_local_zone()'s try/except only covered the TZ-env branch — both
fallbacks unconditionally called ZoneInfo("UTC") and re-raised.
Fix (two parts):
1. services/local_backup.py — return type widened from ZoneInfo to
tzinfo, the UTC fallback is wrapped in its own try, and the
last-resort fallback returns datetime.timezone.utc (stdlib, no
IANA DB needed). str(timezone.utc) == "UTC" so the response shape
on /api/local-backup/status is unchanged. The astimezone call in
_calculate_next_run accepts any tzinfo — no other call sites
affected.
2. requirements.txt — pin tzdata>=2024.1; sys_platform == "win32" so
the next Windows installer build ships the IANA DB, and any non-
UTC TZ value (e.g. Europe/Berlin) resolves correctly. The stdlib
fallback can only ever give UTC. Linux/macOS unaffected by the
platform marker — they already have the system tz database.
The Re-print and Schedule modal toggles for Flow Calibration and Nozzle
Offset Calibration accepted "off" correctly and flowed it through to the
project_file MQTT publish — Bambuddy sent extrude_cali_flag: 2 and
nozzle_offset_cali: 2 per the "1 = run, 2 = skip" reading inherited from
the #1478 / #1682 work. Live test on H2D 01.x: with both toggles off,
the stg queue still scheduled stage 8 ("Calibrating dynamic flow") and
stage 39 ("Nozzle offset calibration"), and the printer ran both at
print start.
Root cause: 2 means "skip the explicit pass but still apply / verify
stored PA via the calibration stage" — close to a no-op K-factor wise
but the per-print physical sequence still runs. 0 is the encoding that
actually drops the stage from stg. A BambuStudio Send-dialog capture
on the same firmware showed 0 for both fields when the user unchecked
the calibrations — contradicting the #1478 commit's read of "BambuStudio
never sends 0."
Fix:
- extrude_cali_flag = 1 if flow_cali else 0 (was: else 2)
- nozzle_offset_cali = 1 if (nozzle_offset_cali and is_dual_nozzle) else 0
(was: else 2)
Dual-nozzle gate stays; single-nozzle prints continue to force-skip the
nozzle-offset cali their head doesn't support (#1682). The 1 (run)
branch is unchanged.
Verified live on the same H2D after the patch: stg dropped to
[29, 13, 4, 14, 3] (cooling, homing, filament change, nozzle cleaning,
vibration comp). Stages 8 and 39 gone.
Vibration compensation is NOT fixed by this commit: vibration_cali is a
bool in our and BambuStudio's wire format, and the H2D firmware queues
stage 3 regardless of the false value. Firmware-side, not solvable at
the dispatch layer with the current field. Filed as a follow-up.
Two warnings polluting every A1 support bundle on healthy prints, both
unrelated to the timelapse-default behaviour the issue actually reports.
1. mqtt_bridge.py's post-bind nudge calls request_status_update on the
real printer's MQTT client to populate the bridge cache without
waiting for the next periodic pushall. The bind frequently races the
TLS handshake, especially on A1 firmware. Skip the nudge when
state.connected is False — the periodic pushall fills the cache
anyway. The WARNING in bambu_mqtt.py stays for the genuinely-
actionable callers (refresh-status API, bug reporter).
2. Post-finish SD-card cleanup (and the symmetric forced-timelapse dir
walk) used delete_file_async's bool return to drive a WARNING when
all candidates failed. A1 firmware self-cleans the SD card before
our cleanup runs — every candidate FTP-DELE returns 550, we burn
the retry budget, then WARN on a successful print. Introduce
DeleteResult.{DELETED,NOT_FOUND,FAILED} so the helpers only WARN
on real network/auth/transient failures. NOT_FOUND advances to the
next candidate without consuming the 2s backoff. User-facing delete
endpoint returns 404 on NOT_FOUND.
The support bundle shipped support-info.json + bambuddy.log, but the raw
shape of the printer's MQTT push_status — the field that blocks per-model
work like AMS Backup detection (deferred in 85fbd7fc) and every vt_tray /
vir_slot / mapping shape regression — was never captured.
Each connected printer now contributes push-status/printer-{i}.json with
{model, firmware_version, captured_at, raw_data}, indexed against
support-info.json["printers"]. Two-pass redaction: a structural walk
drops user-private keys (subtask_name, gcode_file, subtask_id, task_id,
project_id, design_id, profile_id, model_id, gcode_state,
gcode_file_prepare_percent) and rewrites net.info[*].ip to 0.0.0.0
(matches the #1429 VP bridge fix); then the JSON runs through the same
DB-derived sensitive_strings sanitizer the log path uses, catching any
printer name / serial / access code / cloud email that leaked into a
nested string field.
print.cfg, print.option, ams, vt_tray, vir_slot, mapping,
ams_extruder_map, and hardware fields are all preserved — those are the
fields per-model work needs.
Always-on inside the existing debug-logging-required gate; no opt-in
toggle (the bundle is already user-initiated and downloads locally
before the user chooses to send).
Right after the slicer picks a filament for the external spool (vt_tray, ams_id=255),
Bambu firmware pushes a partial vt_tray carrying just {tray_info_idx, tray_color} -
~18 fields shorter than the pushall shape the slicer expects. The #1622 round-4
per-field accumulate (da799447) only carried over prev keys NOT in new, so the
cached vt_tray was replaced wholesale with the 2-field partial. The next 1 Hz
cached-as-base push delivered the stripped dict and BambuStudio rendered the
external slot as invalid (color only, no tray_type / state / k / n / cali_idx /
nozzle_temp_*). Reload restored it because the reconnect-triggered pushall
re-seeded vt_tray, then the cycle repeated. AMS slots didn't suffer because
_merge_ams_dict deep-merged them.
Fix: for every top-level push_status key whose prev AND new are both dicts,
overlay incoming keys onto prev rather than replace. ams is excluded (already
deep-merged). The same shape protects device / online / upgrade_state / ipcam /
upload / net against future firmware partials. net.info IP rewrite is unaffected -
_rewrite_net_info_ips runs before caching and overlay lets the freshly-rewritten
list win over prev when present.
Bundle import never delivered what it implied: BambuStudio's .bbscfg export
strips system processes/filaments, so importing a bundle left users without
process presets and slicing fell back to embedded settings on STL. Bundle
mode also hid the standard tier behind a constrained dropdown, the actual
trap reported here.
Removed end-to-end:
- backend: POST/GET/DELETE /slicer/bundles*, SliceRequest.bundle,
SliceBundleSpec, dispatch fork in library.py, bundle-context params on
the filament-requirements endpoints, bundle-fingerprint cache key in
slice_preview.py, SlicerApiService.{import,list,get,delete}_bundle and
slice_with_bundle, BundleSummary / BundleNotFoundError.
- frontend: BundlePicker + BundleStringDropdown, isBundleMode + every
branch, bundle state/queries/dispatch in SliceModal.tsx, SlicerBundle /
SliceBundleSpec types, three bundle API methods. buildCompatibilityIndex
loses its bundle path; presetCompatibility keeps compatible_printers
plus the @BBL fallback.
- SlicerBundlesPanel turns into a permanent static notice explaining the
removal, alternative import paths, and the new slice-time lookup order
(Imported > Orca Cloud > Bambu Cloud > Standard sidecar fallback).
- i18n: slicerBundlesRemoved.{title,description,alternatives,lookupOrder}
translated across all 11 locales; slice.bundle*, slicerBundles.* keys
removed.
Fixed (surfaced by removing bundle mode):
- _resolve_cloud and _resolve_orca_cloud now force type per slot and pin
from: "system" on the payload before json.dumps. Bambu Cloud ships
type as "printer"/"print" and routinely empty `from`; the BS CLI's
--load-settings parser rejects both with return -5 / "input preset
file invalid". Standard tier already did this; cloud paths now match.
Bridge cache replaced prev state wholesale on each incremental, re-merging
only a 14-key allowlist. Capability/lifecycle fields (cali_version,
print_type, mc_print_stage, device, ...) drained out within one 1Hz tick,
greying out BambuStudio's Device-tab UIs (manage-calibration, AMS-slot
dropdown) once the cache thinned. Most P1S users miss it by timing — they
click Device tab while the cache is still fat from the connect pushall.
Switch to per-field accumulate matching bambu_mqtt.py's internal state
handler: prev keys carry over verbatim when not present in the incoming
push, new values overwrite when present. _merge_ams_dict for partial AMS
blobs unchanged (#1387 / #1371 regression guards stay green).
_SLICER_VISIBLE_STICKY_KEYS removed — new logic is a strict superset.
Round-2 cmd.jsonl from shaddowlink proves the bridge forwards both commands and
responses correctly: ams_filament_setting round-trips with result=success on P1S,
the cached push_status carries tray_info_idx=GFA11/tray_type=PLA-AERO/K-n/cali_idx
intact, and the visible "unload" symptom comes from the slicer's choice of
extrusion_cali_set (push K direct, P1S firmware rejects) vs extrusion_cali_sel
(select by id, both H2D and P1S accept). The open question is what makes the
slicer pick _set vs _sel — likely the info.get_version response Bambuddy
synthesises or the first cached pushall reply the slicer reads at connect.
Round 2 captured neither; the JSONL had slicer_to_bridge and printer_to_slicer
but no direction for the bridge's own synthesised replies.
Same BAMBUDDY_VP_DUMP_WIRE=1 flag now also appends a bridge_to_slicer line for
every bridge-synthesised reply (info.get_version answer, project_file ack,
on-demand pushall response). Capture is in _publish_to_report — the single
chokepoint — gated on a new log_event param; the 1Hz periodic push threads
log_event=False so the JSONL isn't flooded (~60 lines/min/VP) because
dump_wire already covers cache shape per tick.
Diagnostic-only, no data-path change. Default param preserves every existing
call site's behaviour.
The shape-of-payload dump shipped earlier rules out cache wipes —
shaddowlink's round-1 captures show AMS data reaches the slicer
byte-identical to what the printer sent. The remaining symptom
(picking a generic filament in archive mode "unloads" the slot) lives
on the command path, which the snapshot dump doesn't see: it writes
only the cached _latest_print_state and the periodic 1Hz push.
Add append_event() in _debug.py — same env flag, separate file at
<log_dir>/vp_wire/<vp>_cmd.jsonl. One JSONL line per event with UTC
iso timestamp, direction (slicer_to_bridge / printer_to_slicer), MQTT
topic, <channel>.<command> grep handle, and parsed payload. Wired at
two points: mqtt_server._handle_publish for slicer publishes (after
JSON decode so the trace matches what the bridge actually parsed) and
mqtt_bridge._on_printer_raw "everything else" branch for printer
responses (after serial rewrite so the trace matches what the slicer
sees on the wire). Pushall / get_version stay out — both are handled
locally and never round-trip through the bridge.
Bytes payloads get the same \x00-tolerance fix from #927 so
OrcaSlicer's C-string-null publishes parse cleanly; un-parseable
bytes fall back to {"raw": "..."} so every line stays valid JSON.
Four #1712 issues from the 2026-06-04 Orca Cloud integration:
(1) Tier order put Orca Cloud above everything across SliceModal,
auto-pick scoring, dropdown groups, the AMS slot picker, and the
backend precedence. Bambu-Cloud-only users saw their profiles
deprioritised behind an empty Orca tier.
(2) Cross-tier dedup hid a same-named preset in all but the highest-
priority tier. A user with both a local-imported and an Orca-synced
"Bambu PLA Basic" couldn't see the Orca copy as a picker option.
(3) CloudStatusBanner nagged signed-out users with a permanent
"Sign in to Orca Cloud" line at the top of every slice -- even after
explicit logout. Bambu Cloud had the symmetric problem.
(4) ConfigureAmsSlotModal source badges were inconsistent: Orca rows
showed only "Custom" (no source identity), Bambu Cloud built-in rows
had no badge at all, and the orthogonal isUser-driven "Custom" badge
collided with the source badge for cloud user presets.
Order is local > orca_cloud > cloud > standard everywhere it lives
(SliceModal SLICE_MODAL_TIER_ORDER + TIER_BONUS + dropdown tier list,
ConfigureAmsSlotModal sourceOrder, and backend precedence). The order
drives auto-pick + visual group rendering; it does NOT hide profiles.
_dedupe_by_name replaced with _enrich_cloud_metadata: every tier
returns its full list across all three slots (printer / process /
filament). The function still backfills Bambu Cloud filament metadata
from same-named local / orca_cloud / standard entries so cloud
filaments score in pickFilamentForSlot.
CloudStatusBanner silently no-ops on not_authenticated for both clouds;
expired / unreachable still surface. The not_authenticated i18n keys
stay in the locale files dormant.
ConfigureAmsSlotModal: one source badge per row, one colour per source
(green Local / purple Orca Cloud / bambu-blue Bambu Cloud / amber
Built-in). The legacy isUser-driven "Custom" badge is gone; every row
identifies its tier consistently.
Add a BAMBUDDY_VP_DUMP_WIRE=1 escape hatch that writes the bridge's
cached push_status (in) and the 1Hz slicer-facing copy (out) to
<log_dir>/vp_wire/<vp_name>_<direction>.json, overwritten each tick.
#1622's symptom — empty filament dropdown in slicer's AMS slot details
for P1S/A1 but not H2D in non-proxy VP modes — needs visibility into
the actual wire bytes flowing through the bridge to bisect between
"cache is missing fields" and "_send_status_report strips them on copy."
The existing logs prove the bridge is bound and pushing at 1Hz, but
not what's in the payload.
Off by default, single env flag, single file per VP per direction
(bounded disk footprint), failures swallowed at debug so a broken
dump can never break the 1Hz loop. 21 tests pin the helper contract:
disabled-by-default, atomic writes, sanitized vp_name (no path
escape), per-call env check so toggling without restart works.
Reprints reuse the source archive row via the expected-print promotion
branch, but that branch never reset archive.timelapse_path. The stale
path made _scan_for_timelapse_with_retries early-return (so the new
run's MP4 was never downloaded), and _capture_finish_photo_from_timelapse
then extracted the *original* run's last frame and shipped it to Telegram
as the new run's finish photo. Surface was specific to the
timelapse-prefer path (data.timelapse_was_active=true and no external
camera) — fallback live-camera paths were unaffected, which is why this
took a P2S reporter to surface.
Clear archive.timelapse_path at promotion and unlink the stale on-disk
MP4 (best-effort; missing files are logged and skipped). The orphan
unlink also kills a long-standing file-leak: every reprint used to leave
its predecessor's timelapse on disk forever. archive.photos is
deliberately left alone — accumulating one finish photo per run is
correct.
Internal code N9 (from BambuStudio resources/profiles/BBL/machine/Bambu Lab A2L.json),
serial prefix 26A19 (5-char, same shape as H2C's late 31B8B). Capabilities from
Bambu's official A2L specs page: linear rail, single FDM extruder + integrated
cutter/plotter, no Ethernet (2.4 GHz Wi-Fi only), low-rate chamber camera on
port 6000.
The BambuStudio profile's use_double_extruder_default_texture: true flag
describes two TOOL HEADS (FDM + cutter), not dual filament extrusion — A2L
must NOT be classified as dual-nozzle or AMS routing will target the deputy
slot and firmware rejects with 07FF_8012.
Registry updates: printer_models.py, firmware_check.py, virtual_printer/manager.py,
virtual_printer/mqtt_server.py, PrintersPage.tsx, SpoolBuddyAmsPage.tsx.
12 new test cases in TestA2LModel pin every dimension.
A1 and A1 Mini ship without a MicroSD slot at all - there is no
firmware-side "Store sent files on external storage" toggle and the
slicers don't surface a slicer-side equivalent either. The connection
diagnostic was reading state.store_to_sdcard (home_flag bit 11), which
is never set on these models, so the check fell through to fail for
every A1-series user. Combined with the absent slicer UI it left users
thinking Bambuddy was wrong about a setting their hardware does not
have.
New NO_EXTERNAL_STORAGE_MODELS frozenset in utils/printer_models.py
enumerates A1, A1 Mini, and their internal codes (N1, N2S, A04, A11,
A12). has_external_storage() returns False for those, True for
everything else. Unknown models default to True so the check stays
active for future Bambu lineup additions - new no-slot models must be
added to the set explicitly.
The diagnostic now short-circuits to skip before reading
store_to_sdcard when printer.model is in the set. X1, P1, P2S, H2,
and X2D are unchanged - the bit-off -> fail signal is still the right
read for them.
The companion FTP-upload-timeout symptom in the same bug report (ftp
code 28 from BambuStudio when sending to the proxy VP) is a separate
Docker-bridge-mode networking constraint, not addressed here.
The slot card on PrintersPage shows slot_preset_mappings.preset_name
first in its display fallback chain. Three write paths swap which
spool occupies a given slot:
- internal manual assign (inventory.apply_spool_to_slot_via_mqtt)
- internal RFID auto-assign (spool_tag_matcher.auto_assign_spool)
- Spoolman RFID sync (main.auto_sync_spoolman_ams_trays)
Only the first one was reconciling the row. After an RFID-driven
spool change, the card kept surfacing the previous spool's preset
name until the user opened Configure Slot manually.
Reporter saw H2D-1 / AMS-B3 displaying "Bambu PLA Silk+" for a
freshly-inserted Bambu PLA-CF spool. The matching row in
slot_preset_mappings was last written in March when a PLA Silk+
spool had been in that slot - confirmed live in the database.
New backend/app/services/slot_preset_writer.py exposes a primitive
upsert_slot_preset plus two derivation wrappers: one for the
internal Spool ORM object, one for the Spoolman API dict shape.
All three call sites now go through the helper, so the row stays
in lockstep with the assigned spool regardless of inventory mode.
Bug shape exists in both inventory modes and the patch fixes both
per feedback_inventory_modes_parity. The Spoolman path was latent
for users who'd never manually picked a slot preset; the same
"stale row overrides correct catalog name" symptom appeared for
those who had.
Existing stale rows self-heal on the next RFID-driven swap.
Logs device.dev_model_name / dev_product_name / dev_id / project_name
at INFO level once per client session, falling back to device.keys()
if none of the known fields are present.
The MQTT push_status carries the model code in device.dev_model_name
on every message, but nothing in bambu_mqtt.py reads or logs that
field — so adding a new printer model meant chasing the code through
either Bambu cloud or a manual mosquitto_sub. A2L (#1684) was the
case that surfaced this: get_version also failed because the firmware
disconnected right after request topic subscription, so the support
bundle had no way to disclose the model.
INFO level so the line lands in support bundles without enabling
debug. One-shot via _device_id_logged, mirroring the existing
_nozzle_fields_logged flag at line 2095, so push_status spam is
avoided.
Future-proofs against Bambu renaming the field (the fallback dumps
device.keys() so a rename like model_name without the dev_ prefix
is still observable). 3 unit tests in TestDeviceIdentificationProbe
pin all three branches.
N1 and N2S were flipped relative to every other registry that names
them - firmware_check.py (N2S -> "a1"), virtual_printer/manager.py
(both the model map and the serial-prefix map: N2S -> 039 = A1,
N1 -> 030 = A1 Mini), and printer_manager.py A1_MODELS all agree on
N2S = A1, N1 = A1 Mini. Only printer_models.py had it backwards, so
any path that resolved an A1-family printer by internal code rather
than serial prefix would silently misclassify.
Also fixes the matching comments in LINEAR_RAIL_MODELS - cosmetic only
(both codes were already in the frozenset) but kept the file
self-consistent.
New TestA1SeriesModelIds regression test pins both directions so a
future re-flip fails loudly.
Detects the printer-side variant of install step 4 — many users (esp. on
clean installs) forget to enable this and only notice when their archive
cards have no thumbnails. The diagnostic now catches it upfront.
Detection: read state.store_to_sdcard, which Bambuddy already parses from
MQTT push_status home_flag bit 11 (bambu_mqtt.py:153). Instant, no I/O.
An FTP upload-and-verify probe was tried first and rejected. /cache is
always writable from Bambuddy regardless of the slicer setting — only
BambuStudio's own behaviour changes when the toggle flips, not the
printer's acceptance policy. Confirmed empirically against X1C + H2D
with the slicer option toggled off: probe succeeded, home_flag bit 11
stayed True. So the only reliable signal is what the printer actually
reports about its own state.
Limitation: the printer-side variant only exists on newer firmware
(P2S 01.02 / Bambu Studio 2.6+). On older versions the toggle lives
only in the slicer and the printer never hears about it, so this check
will pass even when the user is missing step 4 in BambuStudio. The
skip-text and the wiki call this out explicitly. A reactive banner on
the no-3MF archive-fallback path is planned as a follow-up to cover
that case.
Statuses:
- pass: state.store_to_sdcard is True
- fail: state.store_to_sdcard is False (-> overall escalates to problems)
- skip: no live state, disconnected, or field never populated
When the user clicked Print Anyway on a filament-deficit warning, the
acknowledgement was one-shot. The route cleared manual_start and
filament_short, then the next scheduler tick re-ran
compute_deficit_for_queue_item against identical spool state, found
the same deficit, and re-set both flags. The item bounced between
"user said anyway" and "scheduler re-blocked" — every Play click
returned 409, every confirm got rolled back on the next tick.
Add a persistent acknowledgement flag on the queue item:
- New column `skip_filament_check` on print_queue. SQLite + Postgres
migration branched on is_sqlite() so Postgres doesn't reject
DEFAULT 0 on BOOLEAN.
- PrintQueueItemCreate + PrintQueueItemResponse schemas + the
TypeScript types carry the field.
- POST /print-queue/{id}/start with skip_filament_check=true now
ALSO sets item.skip_filament_check = True (not just clearing
manual_start / filament_short).
- PrintScheduler._block_on_filament_deficit short-circuits to
False — no compute, no flag-setting, no notification — when
item.skip_filament_check is True. We trust the operator's
decision and stop fighting them.
- PrintModal at queue-creation time threads
skip_filament_check=true into the create payload when the user
clicks Print Anyway on the frontend deficit warning, so a print
that was warned-then-acknowledged at add-to-queue time goes in
pre-acknowledged — scheduler never blocks it on first tick.
Flag is not auto-cleared on spool swap by design: if remaining is
now sufficient, the check returns no deficit anyway, so the flag
is moot. Auto-clearing would add lifecycle complexity without
changing behaviour.
AMS Backup awareness (the other half of the discussion) intentionally
NOT included — verified the H2D's bit-26 of print.cfg toggles with
the printer-side AMS Backup setting, but the X1C's cfg has a
different shape entirely and verifying every model family isn't
realistic. Silently under-warning would be worse than always
per-slot. The check stays single-slot for now.
When a print targets a single plate from a multi-plate 3MF, both the
internal Filament Inventory tracker and the Spoolman-mode tracker parsed
the 3MF without a plate filter and summed every plate's filament — so a
single lid print debited the spool the entire file's grey + black totals.
The 3MF parser already supports plate_id (queue pre-flight uses it at
print_queue.py:254/:286). Plumbed it through both dispatch paths:
Queue path:
- PrintSession gains a plate_id field; on_print_start queries the
printer's currently-printing queue row and records queue_item.plate_id
onto the session.
- _track_from_3mf accepts plate_id and passes it to the extractor.
- store_print_data moves its existing queue-item lookup above the
extract and uses queue_item.plate_id as the plate filter.
Direct-Print path (reprintArchive / printLibraryFile — never goes
through the queue):
- _print_plate_ids dict added in main.py, parallel to _print_ams_mappings.
- register_expected_print accepts plate_id and stores it; the 2 sites in
background_dispatch.py and the 1 site in print_scheduler.py now pass
it (resolve was already happening, just needed reordering before the
register call so the value is available).
- Expected-print promotion in main.py injects _print_plate_ids[archive_id]
into the session, guarded so a queue capture wins over the dict.
- _get_start_plate_id helper feeds plate_id into all 3
_store_spoolman_print_data call sites; spoolman_tracking.store_print_data
takes the caller value first, falls back to queue_item.plate_id.
PrintArchive.filament_used_grams stays file-level summed by design
(#1593's contract — the archive describes the file, not the run); only
the per-run usage attribution becomes plate-aware. Single-plate direct
prints resolve to plate_id=1 → plate 1 = whole file, identical to the
prior no-filter behaviour.
Round 1 (b6636053 + 4ffefa60) shipped the keepalive parser, 1.5x idle
disconnect per MQTT spec section 4.4, and a per-minute status-push
diagnostic. Reporter's follow-up pcap showed the round-1 logic was
correct as designed, but the actual root cause sits one layer down:
the same OrcaSlicer install that stays connected to a real Bambu P1S
indefinitely sends zero MQTT packets after the initial CONNECT /
SUBSCRIBE / pushall / get_version burst - no PINGREQ at all - so any
spec-compliant server disconnects it at keep_alive x 1.5.
Real Bambu firmware does not enforce section 4.4. The reporter's
identical Orca install holds idle sessions against real hardware on
the same network. Spec compliance was itself the regression.
Fix: after CONNECT/auth, drop the application-level read timeout
entirely (read_timeout = None) and set SO_KEEPALIVE on the underlying
socket so the OS TCP stack reaps dead connections within a few
minutes. The 60s pre-CONNECT cap is preserved - a client that opens
TCP but never sends CONNECT still gets reaped. Negotiated keepalive
is still parsed and now logged at INFO ("MQTT client X authenticated
(negotiated keepalive=Ys, idle disconnect disabled)") for support-
bundle visibility.
After this ships, OrcaSlicer should stay connected to the VP
indefinitely while idle and reconnect cleanly on real network drops.
The publish_json code -4 and -6010 errors reported in the original
thread were downstream of this disconnect and should also clear.
The Profiles page edit modal (shared by BL Cloud / Orca Cloud / Local
Profiles) renders filament_type from backend/app/data/filament_fields.json
via GET /cloud/fields/filament. The curated 11-option list pre-dated Bambu's
CF/GF lineup expansion, so PLA-CF and most carbon/glass-fiber variants were
unselectable — saved presets carried the wrong material code at dispatch.
Expanded to 25 BambuStudio-aligned options grouped by family: PLA (+ CF/GF/
AERO), PETG (+ CF), ABS (+ GF), ASA (+ CF/GF), PC, PCTG, PA family (+ CF/
PAHT-CF/PA6-CF/PA6-GF), PET-CF, TPU, PPS family (+ CF/GF for X1E), PVA, HIPS.
K-profiles editor unaffected (picks filament_id, not filament_type).
Reporter on a multi-printer farm with 40+-plate runs needed to walk to
the printer with the right physical plate, but the queue and the
scheduling modal didn't surface curr_bed_type the way the archive card
already did.
New utils/threemf_tools.extract_bed_type_from_3mf helper (per-plate) so
both the queue API and the /plates endpoint can return per-plate values.
PrintQueueItemResponse.bed_type populated from archive.bed_type /
library_file.file_metadata['bed_type'] as the default, then overridden
per-plate via the helper when item.plate_id is set. /archives/{id}/plates
(and library equivalent) include bed_type in each plate object.
Per-plate accuracy matters because archive.bed_type is captured at
ingest as only the first plate's value (services/archive.py:235) -
a 40-plate 3MF mixing PEI + Engineering returns PEI at the archive
level for every plate. The helper re-reads the 3MF and returns the
truth.
Frontend: queue card meta row + PlateSelector per-plate row + PrintModal
header all render bed icon + canonical label via the existing
getBedTypeInfo() helper, same as the archive card.
Bambuddy's project_file MQTT payload hardcoded "nozzle_offset_cali": 2 (skip),
giving users on H2D / H2D Pro / H2C / X2D no way to control the same toggle
BambuStudio exposes. Critical for diamond-nozzle setups that must keep the
calibration off.
start_print() now takes a nozzle_offset_cali kwarg; the value is encoded as
1 (run) or 2 (skip) and gated on is_dual_nozzle so single-nozzle machines
always send 2 even if a stale flag arrives. The kwarg threads through
printer_manager, both background_dispatch sites, and print_scheduler so
every dispatch path respects the per-item setting.
print_queue gains a nozzle_offset_cali column (DEFAULT TRUE, is_sqlite()
branch for Postgres BOOLEAN). Settings default key default_nozzle_offset_cali
defaults to TRUE to match BambuStudio. Schemas updated across print_queue,
library FilePrintRequest, archive ReprintRequest, settings.
PrintModal renders the new toggle only when the selected printer is dual-
nozzle (printer-mode: nozzle_count===2; model-mode: DUAL_NOZZLE_MODELS).
SettingsPage default-print-options row + QueuePage bulk-edit tri-state both
hide unless any registered printer is dual-nozzle. Labels reuse the existing
settings.default* keys so the only new i18n strings are
settings.defaultNozzleOffsetCali / Desc and queue.bulkEdit.nozzleOffsetCali
- real translations in all 11 locales.
on_printer_status_change fires from MQTT _on_connect BEFORE the first
push_status round-trips, when PrinterState is still on construction
defaults (state="unknown", subtask_name=""). The connected-edge
reconcile was treating that degenerate state as evidence and
synthesising aborted PRINT COMPLETE for every in-flight archive on
every Bambuddy restart. The reactive PRINT COMPLETE then created a
duplicate archive (lookup misses on cleared _active_prints), so
filament got deducted twice.
Two-layer guard: gate the reconcile spawn on a real state.state, and
make _is_active_archive_stale return not-stale on unknown/empty input
as defensive fallback. #1542 behaviour preserved — real stale archives
still get caught the moment a real push_status arrives.
_watchdog_print_start now treats subtask_id-advance as Phase A
"command landed", not as final success. Phase B (180s) keeps watching
for the active-state transition; if it never arrives — printer
accepted the file but stalled (cloud+LAN re-auth after a power cycle
on old firmware was the reported trigger) — revert the queue item to
'pending' instead of leaving it stuck in 'printing' until container
restart. Phase B skips force_reconnect because subtask_id-advance
proves the project_file landed; a reconnect mid-parse would trigger
0500_4003 (#1150). Phase A's H2D 50s FINISH→PREPARE tolerance (#1078)
is preserved by Phase B's 180s headroom.
ThreeMFParser._parse_3dmodel left XML-escaped values raw, so a Title of
"PCB Vise & Solder Station" landed in the DB as the literal "&" and
React re-escaped it on render to "&amp;". Apply the same
loop-until-stable html.unescape() the sibling ProjectPageParser already
uses, uniformly across all <metadata> values.
Same drop: rewrite the VP archive-name-source tooltip in all 11 locales.
BambuStudio 2.7.x (PrintJob.cpp:314-325) overwrites the user-typed
Send-dialog name with the slugified 3MF Title field whenever one is
present, so the previous "handy if you renamed the job in the send dialog"
copy was false. New text spells out the actual behavior; both Filename
and Metadata modes often produce the same string for that reason.
The 50000-51000 docker-compose port range spawned ~2000 docker-proxy
host processes (~3.5 GB RSS) under Docker's default userland-proxy.
The 1001-port pool was symptom treatment — collisions only matter for
multi-VP-on-shared-bind, but the cost was paid by every install.
Each VP now gets a non-overlapping 10-port slice computed from its id
(VP 1 -> 50000-50009, VP 2 -> 50010-50019, ...). Class constants are
gone; VirtualPrinterFTPServer takes passive_port_min/max instance args.
Wraps modulo PASSIVE_MAX_SLOTS = 100, with the existing 10-attempt
random retry as same-slot collision fallback.
Compose default narrowed to 50000-50029 (3 VPs). Proxy-mode VPs forward
the real printer's full range and stay on the separate TCPProxy
constants. Compose comment rewritten to acknowledge Linux multi-service
hosts as a primary bridge-mode audience and drop an over-stated
"confirmed by reporter" claim about userland-proxy=false.
Two bugs in PrintScheduler._check_previous_success:
- Lookback excluded 'cancelled' so user cancellations were walked past
- Lookback included 'skipped', so one skip cascaded indefinitely
Swap to ['completed', 'failed', 'cancelled', 'aborted'] and accept
both 'completed' and 'cancelled' as predecessor success. Real
'failed' / 'aborted' still gate.
One-shot migration in run_migrations resets only the skipped items
whose true predecessor was cancelled — surgical reversal of the exact
bug fingerprint, leaves genuine failure-gated skips alone. Portable
across SQLite and Postgres, idempotent on re-run.
Cloudflare on bambulab.com now serves cf-mitigated=challenge to plain
Python TLS handshakes. Use curl_cffi.AsyncSession with impersonate="chrome"
for the two bambulab.com fetches (index page + per-model JSON); wiki and
CDN paths stay on httpx. HTTP User-Agent stays honest "Bambuddy/1.0" —
only TLS-handshake bytes match Chrome, per the compliance commitment.
Soft dependency — falls back to httpx with a startup warning when
curl_cffi isn't importable; wiki-based version detection still works.
asyncio holds only a weak reference to tasks returned by
``create_task``. Fire-and-forget callers that discard the return value
let the event loop GC the task before it finishes, logging
``Task was destroyed but it is pending!`` with no traceback. The #1648
support-bundle review surfaced 94 such warnings in 8 days of v0.2.4.5
-- the silently-vanished exceptions reach support bundles as opaque
GC notices instead of actionable errors.
New backend/app/core/tasks.py::spawn_background_task(coro, *, name=None)
is the one place in the codebase that calls asyncio.create_task. It
stores the task in a module-level set, attaches a done-callback that
auto-removes on completion AND surfaces any uncaught exception via the
logger with the originating traceback, and accepts name= so a leak
source is traceable through /tracebacks and the log line. Cancelled
tasks don't log (a shutting-down service is not an error).
Migrated the 16 truly-orphan create_task call sites to the helper:
main.py (8):
reconcile-stale, cooldown-poweroff, energy calc, smart-plug,
maintenance-check, photo-then-notify, layer-timelapse,
scan-timelapse, print-scheduler, notify-no-archive (the last one
was hand-rolling the same pattern with task + no-op done_callback)

Reporter on Bambu Studio 2.7.1.57 + X1C saw the Send modal stuck at
"Downloading" after sending to a Queue-mode VP. Delete-from-queue and
even Auto-Dispatch ON + a successful real print didn't release it.
Root cause: BS 2.7.x flipped the Send sequence from
MQTT project_file -> FTP upload -> done
to
FTP verify_job -> FTP .3mf -> MQTT project_file.
The #1280 fix sets gcode_state=FINISH in on_file_received (after the
FTP upload). Under the new order, the synthetic project_file ack in
_send_print_response then runs and overwrites _gcode_state back to
PREPARE. The 1 Hz cached-as-base push stream carries PREPARE forever,
the slicer never sees the FINISH transition it waits for, and the
modal sits stuck. Auto-Dispatch ON shares the cause: the real
printer's PREPARE->RUNNING->FINISH on the bridge gets masked by the
local _gcode_state override in _send_status_report.
Re-fire set_gcode_state("FINISH", filename, prepare_percent="100")
1.5 s after the project_file ack for every non-proxy mode (queue /
archive / review). The 1.5 s window lets the slicer see at least one
PREPARE push on the 1 Hz cycle so the transition reads as
PREPARE -> FINISH, matching what the slicer expects. Proxy mode is
exempt -- there the real printer drives the bridge state and a
synthetic FINISH would clobber a real PREPARE/RUNNING transition.
The scheduler cancels any in-flight timer when a new project_file
arrives so a retrying slicer doesn't end with two competing FINISH
timers. The pending timer is also cancelled on stop_server.
Non-proxy VPs (Archive / Review / Queue) with a target printer set up
a live-mirror bridge that forwards the slicer's MQTT and RTSPS auth
bytes through to the real printer. The slicer holds one code in its
profile (the one it bound the VP with), and that code has to satisfy
both the VP listener and the real printer at the far end of the
bridge. If the codes diverge the bridge silently fails at the second
hop — slicer reaches .49:8883, FINs before sending a ClientHello,
retries identically. The wiki framed the code-match requirement as a
camera-only concern; it isn't, all bridged protocols inherit.
Fix removes the foot-gun instead of re-documenting it. When a target
is selected on a non-proxy VP the access-code field switches to a
read-only display showing the target's code with an Eye-toggle
reveal; the backend auto-inherits on every create / update (any
explicit access_code submitted alongside a target is silently
overridden as belt-and-braces for non-UI clients). The required-when-
enabling check now treats target-set as satisfying the access-code
requirement. Standalone (no-target) non-proxy VPs still get the
editable input + Save button.
One-shot startup migration corrects any pre-existing mismatched
rows: SELECTs diverged VPs and logs one INFO line per row for the
audit trail, then UPDATEs via correlated subquery. Idempotent and
portable between SQLite and Postgres.
Bambu's end-gcode lowers the bed at gcode_state=FINISH. Bambuddy's
live-camera grab captured the bed already dropped, ruining the photo
framing. Source the photo from a brief Bambu timelapse instead —
firmware stops timelapse recording AFTER toolhead parks but BEFORE
bed-drop runs, so the last frame frames the finished print correctly.
When capture_finish_photo is on AND the user did not opt in to
timelapse for this print, force timelapse=True at dispatch + mark the
new PrintArchive.bambuddy_forced_timelapse column. After extraction
(success or failure), cleanup deletes the locally-attached file,
clears archive.timelapse_path, and walks the four scanner directories
(/timelapse, /timelapse/video, /record, /recording) trying FTP DELE
against the original filename. User-opted-in timelapses pass through
unchanged.
Resolver lives at services/background_dispatch.py::resolve_effective_timelapse
(module-level so the print queue can reuse it). Both dispatch paths
wired: background_dispatch.py (Print Now / Reprint) AND
print_scheduler.py:_start_print (the queue). Field testing caught the
scheduler gap on the first round — AST regression test now asserts
start_print(timelapse=...) references effective_timelapse, not the raw
item.timelapse, so a future refactor can't silently drop it.
Extractor: ffmpeg -i input.mp4 -update 1 -q:v 2 out.jpg. Decoded
frames overwrite the same output file, so the file left on disk is the
literal last frame regardless of duration. Bambu records one frame per
layer-change, so a 16-layer cube produces a 0.6 s timelapse — the
original -sseof -1.0 approach seeked before the start of the file and
returned frame 0 (empty bed). Decoding every frame is fine; Bambu
timelapses are short by construction even on hours-long prints.
Migration adds bambuddy_forced_timelapse branched on is_sqlite()
(DEFAULT 0 / DEFAULT FALSE — PG rejects DEFAULT 0 for BOOLEAN).
Verified live on postgres:16-alpine.
Photo-task wait_for budget extends 45s -> 75s when timelapse_was_active
so the notification carries the bed-up photo instead of falling back
to the live-cam grab on slow links.
Scope limit, documented in the camera wiki: prints started directly
on the printer touchscreen / Bambu Handy / Bambu Studio Send bypass
both dispatch paths, so the override doesn't fire there. Future
option: mid-print M981 S1 P20000 MQTT toggle in on_print_start.
Setting description rewritten in all 11 locales to drop the "only
works when timelapse enabled" caveat (Bambuddy now forces it) and
explain the kept-or-deleted behaviour.
Printers added to Bambuddy by hostname/FQDN (e.g. p1s.fritz.box) hit
'invalid IPv4' in _ip_to_uint32_le, so the net.info[*].ip rewrite never
armed and BambuStudio Send went straight to the real printer instead of
the Bambuddy archive whenever the printer was powered on.
Add _resolve_target_to_ipv4(target): IPv4 pass-through, else
socket.getaddrinfo(target, family=AF_INET). AF_INET filter is load-bearing
because net.info[*].ip is uint32 LE and IPv6 can't round-trip. OSError
returns None so a transient DNS failure recovers on the next 30s refresh
tick via the existing not-armed throttle.
Apply the resolver to both the encode call and the host-interface picker
(which also assumes dotted-quad). Armed log line now carries
configured->resolved when they differ, so bad-DNS regressions stay legible
in 'docker logs'. The unresolvable not-armed reason now names the
configured value rather than parroting 'invalid IPv4', distinguishing
'DNS gave a v6 result' from 'user typed garbage'.
Root-caused by @Mape6; @TrickShotMLG02 confirmed the FQDN workaround
on the same release. Pre-0.2.4 these setups worked by accident because
there was no net.info[].ip rewrite at all.
Reported and root-caused by @needo37. Importing a model via the MakerWorld
URL-download feature into a writable external folder (e.g. SMB/NFS-mounted
NAS) saved the 3MF into Bambuddy's internal managed library dir, not the
external mount. The file card showed in the File Manager under the
external folder, but the bytes never landed on the NAS, and the on-disk
copy was UUID-renamed so a find by the original basename matched nothing.
Root cause was save_3mf_bytes_to_library at backend/app/api/routes/library.py:422:
it accepted folder_id but never loaded the folder, never inspected
is_external / external_path, hardcoded the destination to
get_library_files_dir() with a UUID name, and left the LibraryFile row
with is_external=False. So the row's folder_id pointed at the external
folder while its bytes and is_external flag both said "managed/internal".
Same class of bug as #1112, which had been fixed for the multipart-upload
and move paths but never applied to this byte-import path.
Fix mirrors the multipart-upload path directly:
- Load target_folder from folder_id when non-None.
- Feed it to _resolve_upload_destination(target_folder, filename), which
already returns (dest, is_external) and enforces the 403-read-only /
400-unwritable-or-missing / 409-collision rejections.
- Write bytes to dest (real filename for external, UUID for managed).
- Persist the row with file_path=_stored_file_path(dest, is_external)
and is_external=is_external.
The route-layer read-only guard at makerworld.py:256-260 is preserved -
it returns the friendlier error before the upstream download burns
bandwidth - and _resolve_upload_destination's identical check stays as
defence-in-depth for any future caller that skips the route gate.
Thumbnails continue to live under the managed get_library_thumbnails_dir()
regardless of the 3MF's location, matching the upload path.
Reporter @vasmarfas saw X2D archive cards land almost empty - only print
time, no filament weight / layers / MakerWorld link / thumbnail - and
Spoolman filament-usage tracking went silent on the same printer.
Support bundle traces the end-to-end: at print start
backend/app/main.py::on_print_start tries the usual FTP-download dance
for the 3MF, every implicit-FTPS connect attempt to the X2D fails with
`[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1032)`, ~2
minutes later "Could not find 3MF file for print" -> "Created fallback
archive". Fallback path writes file_path="", file_size=0,
content_hash=NULL, no layers / filament / model-link fields. Spoolman
tracking degrades from the same root cause - both depend on the 3MF
metadata parser.
Proximate cause: Python 3.13's default ssl.create_default_context()
negotiates TLS 1.3, the X2D's implicit-FTPS server on port 990 rejects
the ClientHello. Same family as the P2S 01.02.00.00 bug from #1401
(post-Python-3.13 TLS-1.3 breakage), different wire-level failure mode
(P2S completes the handshake and truncates with 426; X2D fails the
handshake outright).
Same fix shape: add X2D to backend/app/services/ftp_profiles.py with
cap_tls_v1_2=True, plus N6 -> X2D SSDP alias. Every other model stays
on negotiated TLS 1.3.
Honest caveat: hypothesis-driven trial, not a confirmed root-cause fix.
WRONG_VERSION_NUMBER could equally describe the X2D switching to
explicit FTPS (AUTH TLS on plaintext greeting) or moving FTPS to a
different port - either would need a different code path. Reporter has
been asked to test this build; if the cap doesn't clear it the registry
slot stays useful and the next diagnostic round goes to openssl
s_client from a network-adjacent host.
The hourly AMS sensor recorder dispatched humidity and temperature alarms
for every unit above threshold without checking whether the unit was
actually loaded. Empty AMS units still report ambient readings, so users
with one loaded + one empty AMS got useful alarms for the loaded one and
hourly noise for the empty one. Disabling the whole alarm category killed
both — not a real choice.
New _ams_has_filament helper inspects tray_exist_bits (hex bitmap, "0" =
empty) with fallback to the tray array's tray_type strings for shapes
where the bitmap is missing. The recorder gates the alarm dispatch on
this check per-AMS-unit, so a multi-AMS printer with one loaded + one
empty still alarms on the loaded one.
Sensor history still records regardless of the gate so the System page
humidity charts stay continuous — only the outbound notification is
suppressed. 9 unit tests cover the bitmap-zero case, bitmap-missing
fallback, garbage/blank/int bitmap edges, and defensive malformed tray.
_refresh_ip_encoding had 4 silent early-returns. When the rewrite
silently no-op'd on a user's setup, the only signal was the absence of
the "armed" INFO line, and diagnosing which path was firing meant
grepping the source.
Each path now emits one INFO line naming the specific reason. A
_not_armed_reason dedup field throttles to one line per state change,
so an idle unarmed bridge doesn't spam every 30s refresh tick. Cleared
on successful arm so regressions re-emit.
Not a fix for #1429 itself — the bridge logic is unchanged; this just
turns the silent failure into visible signal so the next "fix didn't
work for me" report can be triaged in one round-trip.
H2C was in _DRYING_UNSUPPORTED_MODELS. Move to _DRYING_MIN_FIRMWARE
with the same 01.02.00.00 floor as H2S / P2S. Both SSDP model codes
the H2C advertises (O1C single-nozzle, O1C2 dual-nozzle) get the
same gate so supports_drying() fires correctly regardless of which
form is stored on the printer record.
The existing connection diagnostic proved TCP + TLS + auth + SUBSCRIBE but
not that the printer was actually publishing reports. A wrong-cased serial
passes mqtt_auth because the broker accepts the subscription regardless;
the user-visible symptom is empty AMS / no K-profiles / no custom filaments
in the slicer Device tab because the VP cached state is empty. Bambuddy
already logged the actionable hint at bambu_mqtt.py:498 but only to
container logs.
New printer_publishing check turns that warning into a structured
diagnostic result. Pass = bridge has seen at least one report since the
last (re)connect; fail = zero reports across the wait window with fix-text
pointing at the case-sensitive serial. Bounded 10s poll on the on-demand
UI route, no wait on the support-package gathering path so bundling stays
fast. Exits the moment a message arrives — typical wall-clock is 1-2s.
Frontend renders an elapsed-seconds counter plus a "Listening for status
report — up to 10s" hint during the pending state so the wait doesn't look
hung. PUBLISH_WAIT_DEFAULT_SECONDS pinned on both sides.
report_messages_since_connect exposed as a public property on
BambuMQTTClient so the diagnostic doesn't reach into private state.
The Scheduled Local Backups time-of-day picker was interpreted as UTC by
_calculate_next_run, so a UTC+3 user had to enter 18:00 to get a 21:00
local backup. The UI labeled the field "UTC" but it was still surprising.
Picker is now interpreted in the container's local timezone, resolved
from the TZ env var via zoneinfo.ZoneInfo (same source the Support page's
environment.timezone shows). UTC fallback when TZ is unset or
unrecognised. The /local-backup/status endpoint exposes the resolved
zone, and the UI renders it next to the field via a new
backup.localTimeHint i18n key with real translations in all 10
non-English locales.
One-time behaviour change for users who entered a UTC time as a
workaround: the first scheduled cycle after upgrade will run at their
local TZ offset earlier than expected. Re-enter the time as local once
and it is correct from then on. No migration is shipped; migrating
around a DST boundary would be ambiguous.
